Process for producing an mas glass with high etch homogenieity

Abstract

A process for producing an MAS glass is described wherein 10 to 40 mol % of MgO, 5 to 30 mol % of Al2O3 and 40 to 70 mol % of SiO2 or precursors of these raw materials are mixed, the mixture is melted, the melt is cooled and comminuted to afford particles of less than 10 mm, preferably less than mm and particularly preferably less than 2 mm in diameter. The particles are heated and melted and the melt is cooled, as well as an MAS glass obtainable by this process, and a component including the MAS glass and the use of such a component are also disclosed.
